Nice group, I was tempted by that Invicta you have there, looks good.
I picked this up, many years ago, early 80's, battery had died, sat it aside as I picked up a new watch and sort of forgot about it all these years, just the watch no band sitting in my knife drawer. Until my new watch that I recently put a new band on, the deployant clasp was defective, had to send it back, so I dug this up and ordered a battery for it, checked inside, was worried it had leaked during all those years, hadn't luckily! UPS guy arrives with the battery, pops it in and ticking away, excellent time keeping so far for sitting all these years.
Says the movement is Japan 7123 and 506 L R the one is the movement the other is maybe the date it was made?
Dunno, but glad to have it to wear during the wait, I do need to get the crystal cleaned up, pretty scratched up it would take a lot to get it like new again I'm afraid
